Feeds Works for Machine Tools

Chamberlain & Newman - patent attorneys
This invention relates to new and useful improvements in feed works for machine tools and refers particularly to mechanism for operating the head that carries the cutting tools. While the feed works is susceptible of a wide application to machines of various types, yet it will be seen that it is illustrated in connection with a novel type of multiple spindle machine of the general type and character shown and described in a prior patent on a multiple spindle machine # 1,258,089 filed Jan. 9, 1914. This feed works is particularly useful in connection with a machine of this type or in fact any machine which includes an operable tool carrying slide that is adapted to be operated by a feed screw, as is the case-with this machine, which is now commercially known as the Mult-AuTMatic. The purpose of this invention is to provide an improved design of feed works which does not alone perform a simple feeding operation of the tool carrying slides, but one which includes a quick forward movement of the feed screw to bring the cutting tool in position for operation; and which further comprises means for then connecting the feed for the cutting tool; further to provide automatic means for tripping the operating or cutting feed when its work is completed and quickly, returning the slide to its starting position preparatory to a further operation. A further object of the invention is to overcome .objections now existing in other forms-of-feeds, whereby a more powerful and rigid feed may be had including the use, of change gears, affording an opportunity for cutting exact pitches, and the ability to operate said feed works by hand independent of the other feed works on the machine sending it through all or part of its cycle of operations as occasion requires, finally to provide a load weighing or regulating device whereby the load under which the head is feeding may-be predetermined and set to insure uniform operations, and further to provide means whereby an excessive load will engage the clutch to return the head to its position of rest. To provide a screw feed operated by clutches which is rigid and satisfactory, and so that the engagement and disengagement of the clutches may vary with the load under which the head is working; to provide means whereby the head may be fed to a predetermined point within a degree of accuracy in feeding and returning, which has not heretofore been accomplished.

Contour Machining
|
Arthur A. Tomenceak |
Fairfield, Fairfield County, CT |
Abstract
The disclosure relates to techniques in equipment for the machining with single point tooling of non-ciruclar shapes and contours. The procedure according to the invention involves the use of a rotary cutting head, carrying one or more cutting tools, arranged to be advanced axially to accomplish internal boring or external turning of non-circular shapes. The cutting head, which may be considered either a boring head or a turning head, depending on whether the cut is taken internally or externally, is mounted for controlled advancing and retracting movements along its rotational axis. The curring tools themselves, which are carried by the cutting head, are mounted for controlled radial extending and retracting movements as a function of the rotational position of the spindle. The extending and retracting movements of the cutting tool or tools is controlled by means of a pre-shaped contour cam mounted in fixed relation to the workpiece. During each rotation of the spindle, the cutting tools are extended and retracted according to the pattern of the contour cam, resulting in a contoured, non-circular, cutting or boring of the workpiece. Because the tool-carrying spindle rotates, while the work remains stationary, the centrifugal force created by the spindle rotation is used to great advantage to assist in controlling movement of the tool slide in accordance with the path determined by the contour cam. The process and apparatus of the invention can be utilized to outstanding advantage in connection with the machining of epitrochoidal chambers for rotary combustion (e.g., Wankel) engines. Significant process aspects of the invention are directed to that end. In this connection, the invention involves the two-stage machining of an epitrochoidal chamber, with the spindle axis of the machine offset a predetermined distance from the plane dividing the two principal lobes of the chamber. In accordance with an important aspect of the invention, by offsetting the spindle axis along the major axis of the chamber, to be located a short, predetermined distance from the transverse dividing plane, an entire half of the epitrochoidal chamber may be machined in one pass of the spindle, using single point cutting tools. The spindle axis is then symmetrically repositioned in offset relation on the opposite side of the dividing plane, to effect machining in a single pass of the other half of the chamber. This extraordinary technique permits exceptional time economies to be realized in the machining of the combustion chamber while at the same time achieving much greater levels of accuracy than has been obtainable with conventional machining processes.

Vertical Lathe with Automatic Tool Change Facility
|
Claude M. Grinage |
Stratford, Fairfield County, CT |
Abstract
The disclosure relates to a tool change system for a vertical lathe or the like which, among other things, greatly reduces the nonproductive time of the machining head. During machining with a first tool, a second tool is selected from a storage library and is transported over to the ram housing from which the ram and cutting tool are supported. The new tool, held by the transfer carrier, remains in a predetermined position with respect to the ram housing, even though the latter is moving in the course of machining operations. When the machining program subsequently calls for a tool change, it is only necessary to retract the ram, and the tool is waiting to be installed. A unique arrangement of torque limiting clutch enables the transfer carrier to follow the movements of the ram housing in the desired manner in preparation for the tool change to be executed. The disclosure also relates to an improved "flow-through" arrangement for effecting tool change, whereby a new tool is slid into position from one side of the ram, while the used tool simultaneously slid out of engagement with the ram from the opposite side. A two-pronged loader simultaneously engages both the new and old tools to effect the desired flow-through tool exchange motion. The new apparatus includes advantageous arrangements for eccentrically mounting right-hand and left-hand tools in the machine ram. Control means are provided for properly positioning the transfer carrier and loader means, taking into account the left-hand or right-hand character of both the new and used tools. Provision for eccentric mounting of the tools enables a much heavier and stronger ram to be employed. Significant reductions are realized in the nonproductive time of the machine, required to effect a tool change, first because the new tool is always in position immediately adjacent and moving along with the ram housing, and second because of the provision for flow-through tool exchange. As soon as the two-pronged loading device has cleared the used tool from the back side of the ram and has withdrawn from the newly positioned tool, the ram can be returned to machining position and machining operations can resume. The balance of the tool change sequence, involving return of the used tool to a transfer carrier and transport by the carrier to the tool library, and the subsequent selection and transfer over to the ram housing of a new tool, all can take place after machining operations have been resumed.

Clamping Means for a Tool Block in the Vertical Boring Machine or the Like
|
Claude M. Grinage |
Stratford, Fairfield County, CT |
Abstract
In a tool change system for a vertical lathe or the like, a new and improved arrangement for clamping a tool block in a tool supporting ram. The new clamping means provides a firm support for the tool block and further includes means for equalizing the clamping forces applied to the tool block and for properly positioning and orienting the tool block in the ram. In accordance with a specific feature of the present invention, the tool block is provided with clamp engaging means on opposite sides thereof and the clamping means comprises a pair of spaced clamping bars engageable with the respective clamping means on the tool block. A common actuating means is operative to move the clamping bars into a tight clamping relation with the clamping means of the tool block. Means are provided for effectively distributing the clamping force applied by the actuating means which comprise a first connecting means for yieldably interconnecting the actuating means to one of the clamping bars and a second connecting means for non-yieldably interconnecting the actuating means to the other of the clamping bars. The non-yieldable second connecting means is arranged on the side of the tool block from which the work approaches.
